User manual EFM/CPS 022

Part number : 61-200-0220

The EFM 022 from software version V4.0 is prepared for using the Charge – Plate - Monitor.

Some older versions can be updated by the manufacturer

Preparation of the unit

• Bring the CPS – Socket in position and put in the EFM 022 vertically

• Screw the ground plate on the EFM 022

• Press the field-plate onto the bolts in touch to the ground-plate

• Connect ground between the HV - Converter and the CPS – Socket

• Connect the CPS – Socket to ground

• Switch on the EFM 022 and wait until „Dist.= 2cm" and a measure value is displayed

• Press and hold the „function/on“-key (approximately 2 sec.) until „change cm“ will appear in

the second line. The pre-selected distance in cm will be displayed in the first line. Press the

„function/on“-key shortly to change the measurement distance, until “CPS - Mode” is

displayed. With each short press of the „function/on“-key the proposed distance will appear

as follows: 5cm => 10cm => 20cm => CPS - Mode

• please wait (do not press the „function/on“- key) until the cps-mode will appear in the

second line.

• The unit is now ready to work as charge plate

CPS - Measurement

• Through pressing of the button at the HV - Converter, a high voltage > ± 1100V becomes at

the two contacts of the appliance generates

• Through touching of the upper field plate with the corresponding contact (+ or -) the

• HV-Converter is loaded the plate. ( see picture )

• The unit recognizes the correct polarity automatically and now is ready for the

measurement

• The internal timer is started with achievement of ± 1000V on the field plate

• The internal timer now counts upward in 0,1sec steps, as far as on the field plate ± 100V is

reached

• In the upper line now it will displayed the pos. or neg. discharge time

• In the lower line, the current voltage is shown on the field plate, until the “function/on"

button is pressed. Then, the voltage measured at this time on the upper plate is shown as

offset voltage in the lower line

• Pressing the function/on“ – key again will reset the display, and it can be started a new

measurement

Maintenance

Do not touch the modulator system to prevent mechanical damages. Avoid any insulating build up

as e.g. dust, paint or varnish dust, condensed water or similar influence.

If it is necessary the modulator system may be cleaned with alcohol and a soft fuzzy-free cloth.

Replace 9V - battery

The 9V block-battery has to be replaced when “Low Battery” appears at the display.

Please switch the unit off before open the battery compartment. Take out the battery and remove

the connector clip. Put the connector clip on the new battery and put it into the compartment. Close

the compartment.
